Obviously Bitcoin is anchored into previous decisions by the effort to keep it immutably perfect hard money. So keeping that in mind, designing it to be immutable from today forward, building it from scratch today, what design changes would you make today?
I never thought of a design but maybe there are features I really would love to see some amendments on for instance is the area with gas fee, gosh I don't know if anyone also complains about the gas fee of Bitcoin because most times I feel very reluctant when having to send out Bitcoin because of its fees and I think since it's pegged to dollar, it is more on other non dollar countries like mine when having to convert the gas fee rate to my local currency and it breaks my heart.
And just as @davis196 said and truly I don't know how possible this could be but it be great having a feature or way of getting to recover once coins just incase there is no access to the seed phrase .
